Using Zotero for Collaborative Scholarship
Zotero offers features to allow you to collaborate other researchers on citation lists and share bibliographies with select users or with the public at large.
See the documentation for creating groups in Zotero.
Many researchers use this feature to collaborate with others on projects or publications, share research findings on topics of interest, build reading lists for instruction, and to provide public bibliographies for unpublished or gated publications. There are many guides available on this topic, including this one from University of North Carolina, and from Wheaton College.
